Make these simple, chewy banana oatmeal cookies using ripe bananas. This recipe is quick to prepare and perfect for a wholesome snack or breakfast treat.

Ingredients

Scale
  • 3 very ripe medium bananas, mashed
  • 2 cups rolled oats (old-fashioned oats work best)
  • 1/2 cup mix-ins (such as chocolate chips, chopped nuts, or raisins – optional)
  • 1 teaspoon ground cinnamon (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. In a medium bowl, mash the ripe bananas until mostly smooth.
  3. Add the rolled oats and cinnamon (if using) to the mashed bananas. Mix well until everything is combined.
  4. Stir in your chosen mix-ins, like chocolate chips or nuts.
  5. Drop rounded tablespoons of the mixture onto the prepared baking sheet, spacing them about 2 inches apart. You do not need to flatten them much; they will spread slightly.
  6. Bake for 12 to 15 minutes, or until the edges are lightly golden brown.
  7. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. This helps them set and become chewy.

Notes

  • Use very ripe bananas; the riper they are, the sweeter and softer your cookies will be.
  • For a gluten-free option, ensure you use certified gluten-free rolled oats.
  • These cookies store well in an airtight container at room temperature for up to 4 days.
  • If you want a richer flavor, add 1/4 teaspoon of vanilla extract to the batter.
